Microseconds (µs)

Time

1×10⁻⁶ s

The microsecond, symbol µs, is a metric fraction of the SI base unit of time equal to one millionth of a second. Defined by applying the standard SI prefix micro- to the second, it provides a precise scale for measuring fast-occurring physical events. Microseconds are routinely used in high-speed photography, acoustics, medical ultrasound imaging, computer hardware timing, and telecommunication signal transmission analysis.
